I want to use PREEMPT_RT with the Ubuntu image for BeagleV-Fire. I see that none of the artifacts from Making sure you're not a bot! includes this patch.
How can I go about customizing the kernel such that I can include PREEMPRT_RT in my image. I might also want to do other changes to the kernel. So an approach where I can modify Kconfig settings for the kernel in general is preffered.
